VAPOR-LAMP.

Specification of Letters Patent.

Patented Jan. 16, 1906.

Application filed September 22, 1904. Serial No, 225,517.

To all whom, it may concern:

Be it known that I, EDWARD SEITZ, a citizen of the United States,residing at Peoria, in the county of Peoria and State of Illinois, haveinvented certain new and useful Improvements in Vapor-Lamps and I dohereby declare that the following is a full, clear, and exactdescription of the invention, which will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to gasolene-vapor lamps.

The object of the invention is the general improvement of such lamps.

A further and important object of the invention is the provision ofautomatic means, in connection with the needle-valve of a vapor-lamp, bywhich when the light is turned off a small vapor-jet may be directedagainst the generator of the lamp, which in burning keeps said generatorhot and ready for instant use.

A further object of the present invention is the provision of apilot-light for use in starting the light at any time and also forkeeping the generator constantly heated, so said lamp may be turned upat any time to burn at its full capacity after having been turnedoif-for instance, as during the day.

A further object of the invention is to provide simple andthoroughly-reliable means for instantly starting a vapor-lamp withoutthe necessity of first generating the vapor.

In the accom anying drawings, forming a part of this app ication, Figure1 is a side elevation of my improved lamp in part section. Fig. 2 is anelevation of a combustion-chamber, showing a valve in the top thereof.Fig.

3 is a horizontal section of a portion of the lamp, taken on line X X,Fig. 2. Fig. 4 is a top view of a flap-valve. Fig. 5 is a horizontalsection of the generator and combustionchamber on line Y Y, Fig. 1.

Many lamps used for burning gasolene-vapor are not what may be termedself-lighting and must always be initially heatedby burning alcohol orgasolene beneath the generator, whereby vapor may be formed to start it,after which the heat from the mantle serves to constantly produce morevapor for the steady burning of the lamp. In view of the disadvantagesfound in such lamps I have devised the lamp shown in the drawings, inwhich A indicates the usual bracket or support for the glass globe B,the same bemg supported in suitable manner by means ward its top, whereit receives a flap-valve F.

(Shown in Fig. 4.) The top of said chamber D is notched at diametricallyopposite sides, as at G, within which the trunnions H of the said valveF rest. At one side of the chamber D and preferably cast therewith isthe generator I, consisting of leg J with which at its lower end thegasolene-feed pipe K is connected, said pipe being either connected withan overhead tank or a tank under air-pressure, as desired. The upper endof J is closed and extends somewhat above the top of the chamber D andlies parallel with the mantle D common to all lamps of this character.Between chamber D and the portion J just described is a pipe L, openingat its top into the said member J, as shown, its lower end carrying acup M and also a needle-valve casing N, whose orifice is beneath thechamber D and directed to enter vapor into the latter. The stem 0 of thesaid valve carries a disk P, with which engages a fork Q, carrying a rodR, the upper extremity having-pivotal connection with an arm S of thesaid flap-valve F, the lower end of the rod being guided in a lug N onthe valve-body, as shown. The generator I is filled with asbestos orother good filtering matter not affected by heat, through which thegasolene passes from the pipe K to the valve N, as indicated by thearrows.

In starting the lamp when first installed alcohol or gasolene is pouredinto the cup M and ignited. The heat therefrom vaporizes the gasolenewithin the generator and the valve on being opened liberates the vaporunder pressure, directing it upward into the chamber D, where it isburned at the mantle, as in all lamps. The heat from the mantle servesto heat the upper extension of the generator, thereby continuallyforming vapor. Now when it is desired to extinguish the light theneedle-valve is turned, as usual, in a di rection to close it until itmeets an arm T, pivoted on a lug U of a portion of the valve memberNdescribed. This prevents the entire closing of the valve and permits avery small portion of the vapor to pass up into the chamber D. With thisaction the disk P by means of the fork Q, pushes the rod R upward,thereby pushing the arm S of the flap-valve upward also to throw thevalve to a horizontal position, it having hitherto occupied an uprightor vertical position, as shown by full lines in Fig. 2. It will be notedthat the said arm S is set at an angle to the valve, so that a movementof the rod R in the direction of its length will accomplish the openingor closing movement freely, as shown by the broken and full lines in thefigure last named. By

closing the top of the chamber D the vapor is confined, and-an outlet isprovided in the wall of the chamber adjacent to the generator through anaperture V, slanted upward, the vapor escaping through said aperture,having been ignited from the mantle before the vapor was entirely shutoff. This flame, which may be made of any size by changing the size ofthe aperture, serves to keep the generator heated continually, so thatwhenever the needle-valve is opened again the lamp is in condition toburn at its fullest capacity. When the valve is opened, the valve F isbrought at once to the vertical position, the mantle receiving the fullhead of vapor ignited from the jet-flame just described. The stop memberor arm T may be operated either by a spring or by gravity, it beingnormally in position to interrupt the movement of the needle-valve. Whenit is desired for any reason to. shut the lamp completely oif, the armis thrown out of the way, so that the plate P can approach the valvecloser and permit the point of the needle to seat.

As shown in Fig. 5, the chamber D and the pipe members J and L areconnected integrally by the webs a and b, the heat from D beingconducted through the metal webs to the entire generator members.

Other means than that shown may be employed for closing the top of thechamber D, and if the flap-valve is used other means for opening andclosing it may be resorted to without departing from the spirit of myinvention. Furthermore, changes may be made in the various other partsof the device as will suggest themselves to the experienced person.
